Review on 🚲 Ultimate Bike Tail Lights: USB Rechargeable, Waterproof LED Safety Rear Light - 2 Packs - 7 Light Modes - Fits Any Road or Mountain Bike by Eric Pavelko

Not happy with it. The biggest problem is that if they don't even last an hour or two on a full charge, they're useless. If they were both fully charged a few days ago they would both be dead after a two hour drive. Today, a full charge, one didn't last an hour, he died before I got home. They are also difficult to put on and take off. The bracket can be swiveled vertically. So when you press the tab to turn off the light, instead of pressing the tab, it rotates to allow you to release the light. The biggest problem, however, is the lousy battery life. I will complain to the seller and see if he will exchange it.
